<h2>Blocks</h2>
</ul>
These statements are grouped into <i>blocks</i>, a block is identified by
curly brackets...There are two types of block.
<ul>
<li>statement blocks
<pre>
	if ( i == j)
        {
          printf("martin \n");
        }
</pre>
The <i>statement block</i> containing the <b>printf</b> is only executed 
if the <b>i == j</b> 
<i>expression</i> evaluates to <a href="../CONCEPT/true_false.html">TRUE</a>.<p>

<li>function blocks

<pre>
	int add( int a, int b)      /* Function definition */
	{
	  int c;
	  c = a + b;
	  return c;
	}
</pre>
The statements in this block will only be executed if the <i> add </i> function
is called. <a href="../EXAMPLES/function.c">Complete function example</a>
